in the invention, in the preparation of the raschel blanket, a face yarn is a hot-wet comfortable polyester functional fiber with the shrinkage rate of 3-5%, a bottom yarn is a polyester fully drawn yarn with the shrinkage rate of 20-30% as a raw material, after the raw material is made into a grey cloth, the contact depth of the fiber and a roller body is controlled by directly contacting with a hot roller body on the surface of the grey cloth and adjusting the pressure, the contact time of the fiber and the roller body is controlled by the cloth moving speed, the warp knitting blanket fiber is bulked at high temperature, in the bulking process, the bottom yarn is heated to shrink along the axial direction of the yarn to form a middle core of the yarn, the face yarn expands transversely to present a fluctuating state and emerges on the surface of the yarn to form a fluffy, loose and soft long yarn, because the face yarn and the bottom yarn present a curled state after bulking, and the curled state formed by the hot-wet comfortable polyester functional fiber is large in bending modulus and the bending directions of the fiber are different, the material is not easy to fall down, and good compressibility and compression resilience can be kept for a long time; in addition, the fibers in the self-crimped form have a low elastic modulus, and can impart a good hand to the fibers.
The curling form of the hot-wet comfortable polyester functional fiber in the face yarn is prepared according to an FDY process, a PET melt is extruded from trilobal spinneret orifices with unequal trefoil lengths on the same spinneret plate, and the cooling speed of the melt at different positions on the cross section is inconsistent after the fiber is self-sprayed due to the fact that the trilobal shape in the adopted spinneret orifices is of an asymmetric structure, and the method is mainly characterized in that: during spinning, the cooling wind speed is high and is between 1.80 and 2.30m/s, the part close to the air blowing opening is cooled earlier and faster, and the part far away from the air blowing opening is cooled slower. When one of the trilobes in the trilobe spinneret orifice is facing the cooling wind, the melt of that lobe cools faster, while the rest of the trilobe cools slower. Under the tension of drafting, the other part in the trilobal shape is easier to draft and thin, and the stress is more concentrated, therefore, on the fiber trefoil cross section, a trefoil stress asymmetric structure can appear, the fiber with asymmetric stress and thickness on the cross section can present three-dimensional curling performance in the heat treatment or stretching process, the curling is good, the elastic recovery rate of the fiber is large, and the thermal damage of the fiber caused by the processing process of false twist deformation can be avoided according to the FDY process.
Has the advantages that:
(1) according to the preparation method of the raschel blanket, the heat-moisture comfortable polyester functional fiber with the trilobal cross section and the three-dimensional self-curling shape is used as the face yarn, and the prepared raschel blanket is good in air permeability;
